Welcome to itwinai

Accelerate AI & ML workflows for Scientific Digital Twins.

itwinai streamlines distributed training, hyperparameter optimization, logging, and modular workflows, so you can focus on science, not plumbing.

Features

🚀 Seamless Scaling: Run training and inference on HPC clusters or cloud with a single CLI command.
🔍 Effortless Logging: Built-in support for MLflow, Weights & Biases, TensorBoard, and more.
🧩 Modular Workflows: Define reusable pipelines for end-to-end experiment management.
🤖 HPO Made Easy: Native hyperparameter optimization with minimal configuration.
🔌 Extensible Plugins: Add custom integrations or contribute new features.

Quick Start

# Install via pip
pip install itwinai

# Launch a simple distributed training job (assuming a valid config.yaml exists)
itwinai exec-pipeline

# View logs in MLflow
itwinai mlflow-ui --path mllogs/mlflow
